VNITED STATES VASHINGTON I. VVOLVERTON, OF HOLTON, KANSAS.

VEHICLE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 635,627, dated October24, 1899;

Application filed March 11, 1899.

To all whom it may concern:

Be it known that I, WASHINGTON I. W01.- VERTON, a citizen of the UnitedStates, residing at Holton, in the county of Jackson and State ofKansas, have invented certain new and useful Improvements inVehicle-Couplings, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to vehiclecouplings, and more particularly to adevice for pivotally securing a singletree upon its support.

The object of the invention is to provide an effective coupling whichwill limit the pivotal movement of the singletree and prevent jarring orrattling of the parts.

The novel features of the invention will be fully described hereinafterand defined in the appended claims, in connection with the accompanyingdrawings, in which- Figure 1 is a perspective view of a portion asingletree and a doubletree connected by my improved coupling. Fig. 2 isa view, partly in side elevation and partly in vertical section, of theparts shown in Fig. 1. Fig.3 is a detail view illustrating the means forlimiting the pivotal movement of the singletree.

The reference-numeral'l designates one end of a doubletree to which issecured a coupling-iron comprising a horizontal plate 2 and avertically-disposed cylindrical casin g 8, provided with a flange 4. Theplate 2 is secured by bolts 5 to the under side of the doubletree, andthe flange 4 rests against the rear side of the doubletree.

To the singletree 6 is secured a coupling-iron comprising a plate 7,secured to the rear side of the singletree, a horizontally-projectingcap 8, and a hollow tapering post 9, depending from the cap 8, whichlatter is formed with an opening 10, registering with the opening in thepost to receive a securing pivotbolt 11, held in place by a nut 12. Thehollow post 9 extends down through the casing 3, which is also oftapering form to fit said post. The cap 8' fits over the upper end ofthe casing 3, and a ring or washer 13, of rubber or like material, isinterposed between the casing and cap to prevent rattling and jar.

To limit the pivotal movement of the singletree, I provide the upper endof the flange 4 Serial No. 708 ,6 8'7. N model-J with a lug 14,whichprojects slightly above the upper end of the casing 3 and enters asegmental slot 15, formed on the under face or edge of the plate 7. Itwill be obvious that the contact of the lug 14 with the end walls of theslot 15 will limit the movement of the singletree upon its pivot-bolt11, the extent of such movement being dependent upon the length of theslot.

While I have shown the singletree in connection with a doubletree, itwill be understood that it may be employed in connection with any othersupport to which the singletree may be attached. Again, while the coupling is primarily designed as a singletreecoupling it might also beutilized as a shaftcoupling without departing from the invention.

I claim- 1. Avehicle-conplingcomprisingahorizontal plate, and avertically-disposed cylindrical casing of tapering form, in combinationwith a coupling-iron comprising a securing-plate, a horizontalprojecting cap, a-hollow tapering post depending from said cap, and apivotbolt.

2. Avehicle-couplingcomprisingahorizontal plate, and avertically-disposed hollow cylindrical casing of tapering form, providedwith a flange, in combination with a couplingiron comprising asecuring-plate, having an integral horizontally-projecting cap, and ahollow tapering post depending from said cap, a yielding washer betweenthe casing and post, and a pivot-bolt extending through said cap andpost, and held by a nut.

3. A vehicle coupling consisting of two members, one comprising ahorizontal plate, and a cylindrical casing of tapering form,providedwith a flange, and an upwardly-projecting ing, and the othermember comprising a securing-plate form ed with a segmental slot, ahorizontally-projecting cap, and a depending hollow tapering post, incombination with a yielding washer, and a securing pivot-bolt.

In testimony whereof I affix my signature in presence of two witnesses.

WASHINGTON I. WOLVERTON.
